From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.6) Gecko/20040115 Description of problem: rpc.mountd can be reproducably killed on our server by trying to mount a directory from it (no extra mount options given on commandline). There are lots of 'udp v4 hw csum failure' kernel messages, which might indicate a hardware problem, but I'm not sure about that. Version-Release number of selected component (if applicable): nfs-utils-1.0.5-3 How reproducible: Always Steps to Reproduce: 1. just try to mount a directory from the server 2. no extra commandline parameters given to the mount command 3. Actual Results: mount: RPC: Unable to receive; errno = Connection refused Expected Results: NFS mount succeeds Additional info: The name of workstation were I try to mount the NFS directory isn't resolvable by DNs, if that matters.
That's quite bad... When I use a DNS resolvable IP on the same workstation, the mount command works and rpc.mountd doesn't segfault.
Created attachment 97332 [details] upstream patch from Chip Salzenberg 2003-09-09 Chip Salzenberg * support/export/hostname.c (get_reliable_hostbyaddr): Fix crash on invalid reverse DNS.
moved to RHEL3 as FC1 shipped with 1.0.6-1 in the end
